REPAIR IPATCH,

Application filed May 4,

This invention aims to provide a .novel repair patch tor use in vehicle tires, novel rneans being provided whereby strength may be combined with adhesiveneee.

it is Within the province oi' the disclosure to iinprove generally and to enhance the utility of devices of that type to which the invention appertaine.

'With the above and other objects in view which will appear as the description pro ceede, the invention resides in the combina tion and arrangement ot parte and in the details ot construction hereinafter described and claimed, it being,l understood that changes in the precise embodiment ot the invention herein disclosed may be inade within the scope et what is claiiiued, Without departing troni the spirit ot the invention.

Figure l shows in. plan, a repair patch constructed in accordance with the inverttion;

Figure il ie a section on the line 'zt-W2 of iiigure i;

Figure 3 ie a plan showing a. inoditied torni ot path;

Figure i ie a section on the line lf-fi of Figure 3;

Figure 5 is a plan showing a inodied torni ot patch, parts being broken away;

Figure G is a section on the line of liigure Figure 7 is a cross sectional view illustrab ing how the device depicted in Figure fi may be need; and

liigure 8 is a cross sectional `view illustratinp,v the use ot the patch delineated in Figure Referring to Figure l. and Figure 2, the patch comprises a iravv cotton body. By Lraw cotton I inean a cotton canvas body which is not treated with rubber, oil, cheini cale and the like. The cotton body l may be niade in any desired Way. In Figures l. and f2, the cotton body i compris-tes a tiret layer 2 and a second layer 3 ot less area than the iirst layer Q, a layer of rubberized :i'abric Ll being supergjiosed on the second layer 3, the layer -t being eoinewhat larger in area than the layer so that the layer i engages the layer about the periphery ot the layer 3, ae shown in Figure 2, although this detail is not insisted upon. The raw cotton layers and 3, Which compose the 1927." Serial No. .1Et3,751.

raw cotton body l, and the layer it ot rubberized fabric, are stitched together in any preferred Way, as shown at A piece of raw rubber (i, ot any desired Size, Weight or torni, ie mounted adhesively on any part of the rubberized layer Ll.

The raw cotton body l is a desirable ele-- nient, in that it possesses great strength. The piece ot .raw rubber shown at 6 is high` ly desirable, also, in that it 'will stick to the tire casing, and enter broken places: but the raw rubber il doce not have inuch tensile streng-th, as compared with a raw cotton body, like ('luA part l. Raw rubber, such as shown at ti, will not adhere to Such a part as the raw cotton body l, and this diiiiculty ie overcome by interpoeing the layer l; of rubberized tabric, the raw rubber G adhering readily to the fabric 4;, and it being possible to etici; the tabii'ic i to the raw cotton body, a patch thus being provided which combines great strength with ability to lill and seal an opening1 in a tire casino.

In the torni delineated in Figures l and 2, the tiret layer 2 ot the cotton body l is considerably longer than the rubberized lay-- er Li, so that the layer 2 has an extension 'i ot considerable length, adapted to be engaged between a riin ti and a casing 9, as in Figure 7, the piece ot raw rubber (i en tering and trilling the break 10 in the cas ing 9.

In liigures i and 4L, parte hereinbetore described. have been designated by numerals previously used, with the suilizxr a. In this torni ot the invention, the extension 7 of Figure l is omitted. Figure 8 sho'we how the patch that appeare in Figures b and 4 may be used in the repairing,f ot a rupture in a tire casing.

In Figures 5 and .6, the raw cotton body is shown as coinprisiiigl a tiret layer 12, a Second layer lel; ot aiuallcr area than the lay er l2, and a third layer 1:3 ot greater area than the layer lli. rlhe rubberized layer i7 ir ot the saine eine as the piece ot raw ruin rubber i@ which is adbesively mounted on the rubberized layer ZiT. The rubberized layer i?, and the layers l2, it and 15, which inalre up the raw cotton liiody il, are stitched together, as shown at What is claiined is i. In a device ot' the claas described, a raw cotton body, rubberized layer, stitchlilo ing uniting the raw cotton body and the rubberized la er, and a piece of raw gum rubberadhesvely mounted on the rubberized layer.

2. In a device of the class described, a raw cotton body, a rubberized layer fasten.-

ing means connecting the rubberized layer with the bod f, and a piece of raw gum rubber :idliesiveiy mounted on the rubberized layer. 10

In testimony that I daim the foregoing as my own, I have hereto aiixed my signa,-
